We clean up /authors, /books and /works Open Library URLs, but have no validation for them at all - they can all be added whenever. We should probably make some changes here:

/authors links should be linked only to artists

/books links should be linked only to releases

/works links should be linked only to works

Additionally:

/publishers links should be cleaned up, and linked to labels - these don't use the usual OL url pattern, but look like https://openlibrary.org/publishers/ISIS_Audio_Books
